LEATHER-CREASING WHEEL.

SPECIFICATION forming part of Letters Patent No. 290,262, dated December 18, 1883,

Application filed February 23, 1883. (No model.)

To all whom it Hwy cancer-1i.-

Be it known that I, HENRY F. OSBORNE, a citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Edge-Greasing WVheels, fully described and represented in the following specification and the accompanying drawings,forming a part of the same.

This invention consists in the combination, with guide flanges having rounding dies formed integrally upon their inner sides, of an intermediate gage-collar and clamping sleeve and nut, the flanges being removable with the gage collar, so that their pattern may be changed and the gage-collar replaced by others of different width. The rounding-dies formed integrally upon the flanges may be combined with the usual ridges for creasing the straps parallel with the edges. Such creases may be made of any ordinary or desired pattern; and to illustrate my invention I have shown three different styles of creasingridges and the straps creased by their application.

The drawings also show the relation of my novel devices to the ordinary parts of a creasing-machine, Figure 1 exhibiting a creasingwheel complete, and combined with the usual pressure-roller,R. Fig. 2 is an edge view of one flange A, provided with my concave circular rounding-die a, andhaving one creasingridge b united thereto. Fig. 3 is a similar view of aflangewith two creasing-ridges formed therewith. Fig. 4. is a similar view of a flange with one ridge b of larger size than that shown in Fig. 2, and Fig. 5 is an edge view of aflange with the die a alone. Figs. 6 and 7 are respectively end and side views of a strap creased by the ridge shown in Fig. 2, the edges of the strap being shown rounded by the die a. Figs. 8 and 9 are similar views of a strap creased by the ridges shown in Fig. 3, Figs. 10 and 11, similar views of a strap. creased by the ridge shown in Fig. 4c, and Figs. 12 and 13 similar views of a strap having the edges alone worked or rounded by the rounding-die a shown attached to the flange A in Fig. 5.

In Fig. l the means of adjusting the flanges, the dies a, and the creasing-ridges b at the desired distance apart is shown at B, and consists of a collar applied to the arbor 0 between the flanges, the whole being clamped upon the I arbor, in the usual manner, by a nut, D. The arbor G is of tubular character, so as to be ap machine, and is thus adapted to be manufactured and sold separately, and is removable from such machine, to be replaced by other wheelswhen desired.

. One of the flanges A may be fastened to the arbor, if desired, or formed integral therewith, and the other is removable, to insert collars of various widths, as B, between the flanges A, the .whole being clamped together by the nut D, appliedto a thread formed on the exterior of the arbor, as usual.

Several widths of straps creased by the flanges and ridges shown in Figs. 2, 3, and 4 are shown in Figs. 6to 11, inclusive, exhibiting the application of the rounded edge to creased. straps; and Figs. 12 and 13 show the effect of the rounding-die a alone, as formed upon the flange A in the manner shown in Fig. 5. In this latter case the edges of the strap are rounded much more perfectly than can be done by hand, while the removable character of the parts AandB enables the operator to changethe wheel at any time, to round the edges of straps either wider or narrower than that shown in Fig. 12. This change in the space between the flanges A A is effected by removing the gage-collar B and substituting another of suitable width, the whole being then bound together upon the tubular arbor O by the nut D,

'as described above. I have found in practice that the only means for rounding the straps edge by a circular die, as a, consists in forming the same integral with the flange, as all the devices produce a line or mark upon the strap, which have consisted of a plain flange held adjacent to a separate creasing or rounding wheel. The, essential feature of novelty in my invention is, therefore, the construction of the rounding-dies a, (0 upon or with the adjustable or separable flanges A A.

The creasing-wheels devised to decorate the middle of the strap have commonly been provided withwaved or ornamentalpatterns alone, and were not therefore adapted to round the edges of the straps at all. My device is intended to crease and round the edges of straps, whether the middle thereof be decorated by other means or not, or to round the edge alone, as shown in Fig. 12, if required. For thelatter plied to the spindle of any suitable creasingpurpose the construction shown in Fig. 5 is especially applicable, the rounding-die a being formed contiguous to the flange and extended outward therefrom as far as is found requisite.

In Fig. 5 the bottom lines of the die are tapered inward toward the center of the flange, to prevent the inner corners from marking or bruising the strap; but such construction is not necessary when the die is combined with creasing-ridges, as shown in the other figures. The object of this invention being to round the edges of straps of different widths, it necessitates the adjustment of the flanges A to and from one another and the use of different gagecollars B, as claimed by me in a previous patent. I do not therefore claim such construe tion, broadly; but finding that the rounding die a cannot be made apart from the flanges A without a crack appearing between the two when the parts are clamped together, and finding that such crack marks the leather disagreeably, I have devised the construction in which the rounding-die is integral with the flange, and thus secure an advantage not attainable when the rounding-dies are formed upon the gagecollarnamel y, that the same dies become applicable to straps of different widths by the mere change of the gage-collars alone, which are cheap and easily removed. It will be seen, therefore,that the present invention is an improvement upon my former one, alluded to above, and that I do not claim the flanges made integral with the rounding-dies apart from the clamping devices shown, as the same are essential to the convenient use of the invention.

I am aware that a United States patent, No. 12,878, has been issued for a series of creasing devices having flanges made at different distances apart, to suit various widths ofstraps but such flanges are not adjustable like mine.

I am also aware that adjustable flanges not clamped tightly upon an arbor with a gagecollar are shown in United States Patent No. 160,231; and I do not therefore claim adjustable flanges, broadly, but only as constructed and combined in the manner herein claimed.

Having thus set forth the nature of my invention and distinguished its novel features from others, I claim the same in the following manner:

The combination, in a removable creasingwheel adapted to fit the spindle of a creasing-machine, ot' the separable and adjustable flanges A A, formed integrally with rounding dies a, the tubular arbor O and nut D, and the removable and changeable gage-collar B, the whole being adapted to round the edges of straps, and to be altered, as described, to fit straps of different widths, substantially as shown and described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

HENRY F. OSBORNE.
